Answer:
Total= $283.33
Step-by-step explanation:
First we need to know how much money we want to pay to lower the bill by 20%.
So: 171600*0.02=34,320
$34,320 is what we need to reach.
Divide this amount by 12 years and then by 12 months:
34,320/12= 2,860/12=238.33
This is the amount you need to save per month to reach the goal.
